Short:    CGraphX gfx extension update 2.04

Type:     gfx/board

The CyberGraphX system was designed to define an independant graphics
standard for graphics boards. We also wanted to continue our development
of graphics extensions. We could include all our knowledge of about 3 years
of gfx board software development (graphics extensions for visiona, domino,
picassoII and now the cybervision64).

CyberGraphX is based on hardware dependant monitor drivers and hardware
independant libraries. This has some advantages: Bug fixes in the graphics
extension or speed optimizations is of benefit for ALL gfx boards that are
supported by the CyberGraphX system.

CyberGraphX allows using of 15/16/24 screens independant of the used
color model. You are able to use the cybergraphics.library functions to
modify this screens.

Currently there are versions for:  Domino
                                   PicassoII
                                   GVP Spectrum
                                   Piccolo Z2/3
                                   RetinaZ3
                                   Cybervision
                                   PiccoloSD64

From now on each update will have its own version number. We left the old
version numbering which was derived from the version number of the main
library (cybergraphics.library). The archive is now called CGraphX20u.lha
because we changed the whole system name from CyBERgraphics to CyberGraphX. 
The product has gone commercial now. A complete archive with some features
disabled will be available in biz/demo soon. Full versions will be available
from Softwood in US or phase5 in Germany. More information about that topic
will follow in the complete aminet archive.


cybergraphics Revision 40.54

   - changed CyberGraphX monitor name from 'CyBERgraphics' to
     'CyberGraphX'
   - fast memory planes are now allocated with MEMF_ANY instead
     of MEMF_FAST
   - fixed problems with fast memory planes and interleaved bitmaps

   - made some changes in the line drawing code

   - added new environment variable KEEPAMIGAVIDEO. If this
     option is disabled, everytime a CyberGraphX display becomes
     frontscreen, AMIGA DMA is switched off. You can avoid this
     by enabling this option.
   - added new environment variable NOPASSTHROUGH. If this option
     is enabled, the monitor switch on every CyberGraphX
     supported board is deactivated. This option is required for
     multi monitor systems.
   - fixed some problems in the lores crsr sprite code
   - added new environment variable PLANES2FAST. With this option
     on, AllocBitmap() allocates non displayable planar bitmaps
     in fast memory
   - fixed clipping rectange bug in MovePixelArray to avoid problems
     with software mouse cursor
   - fixed bottom border clipping bug with bobs/icons in
     BltMaskBitmapRastPort()
   - added planar BltBitmap() replacement
   - added DPMS support call
   - fixed extended BltPattern() complement bug in 24-bit (3bpp)
     mode
   - added new GetCyberMapAttr() tag CYBRMATTR_ISLINEARMEM
   - fixed some routines that didn't handle software cursor
     correctly
   - diverse changes in the software cursor support part
   - extended BltPattern now fully uses blitter in ARGB32 mode if
     possible

   - fixed some problems in AllocBitmap(). Brilliance and DPaint
     brushed failed in 40.50




Monitordriver changes for PICASSOII/PICCOLO/SPECTRUM/PICCOSD64

Revision V1.24

  - made some changes in the softcrsr stuff 
  - fixed enforcer hits at driver startup
  - horizontal auto scrolling works correctly now in 24bit
    (3bpp) mode
  - added DPMS support. Only SD64 supports all 3 levels, the
    other boards only support level 3
  - added software cursor support for 24 bpp mode

  - SD64 driver now uses blitter even in 32-bit pixel modes.
    for template blits.
    filled patterns in 32-bit pixel mode are not possible
    due to a CL-GD5434 bug (Rev JE Production F)

Revision V1.22

  - triple mousepointer bug in PiccoloSD64 24-bit mode fixed.
    Now uses 32-bit ARGB mode.
  - 4MB PiccoloSD64 is correctly detected now.

Revision V1.21

  - (hopefully) fixed SD64 15/16 bit problems




Monitordriver changes for RetinaZ3

Revision V1.4

   - 24bit support added
